The method of acquisition is not known. Approximately 11.69 acres fee (land area) were under the control of the DOD after 1986. Also, approximately 2.67 acres arecurrently owned by DOD. The Army began construction on the military reservation in 1861. Battery Barton Walcott 1 was built in 1899 and armed with an 8-inch breechloading rifle on a disappearing carriage. Battery Barton-Walcott 2 was built in 1899 and armed with an 8-inch breechloading rifle on a disappearing carriage. Battery Craig and Battery Gaston, built in 1902, were each armed with two 3-inch breechloading rifles on pedestal mounts. Battery Cross, built in 1902, was armed with two 5-inch breechloading rifles on pedestal mounts. Battery Milliken, built in 1924, was armed with two 12-inch long range breechloading rifles on barbette carriages. During the 1920's two 155-mm Panama mount field pieces were added to Batteries Craig and Cross. At some point, two 600-gallon underground storage tanks were installed at the Fort. Between 1942 and 1943, the Army added a concrete casemate constructed over each of the guns, three diesel electric engines with evaporation coolers, and two 4,500 gallon diesel fuel tanks installed in vaults to supply the engines. During World War II, the fort included approximately 60 temporary or permanent structures. These structures included quarters, storehouses, classrooms, a post exchange, magazines associated with the batteries and five small arms target ranges. The site was not under other than DOD control during the period of DOD ownership. The Army reported 54.06 acres fee land area and 106.0 acres fee water area excess to General Services Administration (GSA) sometime in July 1973.

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
